[counterintuitive] When an AI coding agent expresses high confidence, the output is more likely correct
Never use AI verbal confidence as a reliability signal. Implement external validation: run tests, use static analysis, verify against specifications. Treat confident wrong answers as the default failure mode, not the exception. If the AI says 'this is definitely correct,' verify it first.
Journey Context:
Humans naturally calibrate confidence: when unsure, we hedge; when confident, we are usually right. AI has no such calibration. LLMs are systematically miscalibrated — they express high confidence on wrong answers as often as or more often than on correct ones. This is especially dangerous in coding because confident wrong code looks plausible, compiles, and may even pass superficial tests. The failure mode is not 'AI says it does not know' — it is 'AI confidently generates subtly wrong code.' Senior engineers who have learned to trust their own confidence as a reliability signal transfer this heuristic to AI, where it is invalid. The most dangerous AI outputs are not the ones that look wrong, but the ones that look right with certainty.
